SEMIROTARYI MOTOR.

' Specification of Letters Patent.

Patented. June 4, 1907.

Application filed July 11, 1906. Serial No. 325,590.

.REMPE, a citizen of the United States of America, and a resident of Kankakee, in the county of Kankakee and State of Illinois, have invented certain new and useful Improvements in Semirotary Motors, of which the following is a specification.

This invention relates to that type of motors in which the piston has reciprocation in a curved piston chamber, and has for its object to provide a'simple and efficient structural formation and combination of parts whereby a certain and efiective reversal of the motive fluid is attained at the end of each stroke of the piston, all as will hereinafter more fully appear.

In the accompanying drawings :Figure 1 is a horizontal section on line m-:c Fig. 2, of a motor constructed in accordance with the present invention. F ig.'2 is a vertical section of the same on line ww Fig. 1. Figs. 3 and 4 are vertical transverse sections on line m .'1; Fig. 1, illustrating the two positions of the valves of the motor.

Similar numerals of reference indicate like parts in the several views.

Referring to the drawings, 1 and 2 are a pair of circular sections joined together by flanges 3 to constitute the stationary housing or the piston chamber of the motor, and to this end the respective sectionsare formed with counterpart recesses which together constitute the piston chamber, as shown.

4 is a radial abutment head forming a part of the section 1 aforesaid, and intersecting the piston chamber and adapted to have con- ,tact bearing against the periphery of the piston hub hereinafterdescribed. Such abutment head is chambered out to form the induction and eduction chambers 5 and 6 of the motor, which chambers ,are, arranged, side by side and are provided with inlet and outlet passages 7 and 8, for the motive fluid, and; with pairs of opposed induction and eduction passa es 9, 10, 11 and 12, communicating with t e respective ends of the pi ton chamber, as shown.

i 13 is the motive fluid induction valve arranged transversely in the induction chamher 5, and provided with valve heads at each end ada ted to alternately seatoutwardly upon val ve seats which form part of the induction passages 9 and 10, between the respective ends of the piston chamber and the said induction chamber 5, the arrangement being such that with one passage closed the other passage willbe open, and vice versa.

14 is the motive fluid eduction valve arranged transversely in the eduction chamber 6, and provided with valve heads at each end adapted to alternately seat inwardly upon valve seats which form part of the eduction passages 11 and 12 between the respective ends of the piston chamber and the said eduction chamber 6, the arrangement being such that with one passage closed to the piston chamber the other passage will be open thereto, and vice versa.

15 is the piston comprising a pair of wings carrying a packing having'a moving fit in the piston chamber and provided at one side with a carrying hub 16, which in turn ,is securedto the motor shaft 17 turning in bearings formed therefor in the main casing of the motor; such bearings having an axial arrangement in relation to the curved piston chamber, as usual in the present type of motors.

18 is a spring packing bar arranged in a recollars 19 near their extremities and coiled springs 1 9 secured at their inner ends to said extremities. The coiled springs carry heads 20 on their outer ends, which in the final travel of the piston in either direction are ada ted to simultaneously and positivelypus upon and operate the induction and eduction valves 13 and 14 by the arms-com pressing the coiled springs 19 between the collars 19 and the heads 20 to cause a reversal of the inlet and outlet flow of the motive fluid in a serial manner durin the continuedoperation of the motor. The right angle arms have their inner parts located perpendicularly of the piston and their outer parts parallel with the piston.

The present motor is especially adapted for use as a motive power for washing machines of the type in which the stirring plunger has a rotary reciprocating movement, in

that the shaft of the present motor can constitute a part of the carrying shaft of the stirring plunger aforesaid.

Having thus fully described my said inventi'on,vvhat I claim as new and desire to secure by Letters Patent, is

A semi-rotary motor comprising a radial. abutment having transverse induction and eduction valves, a piston, plates secured to pesite sides of the piston, pairs of right all 0 y g e arms carried by each plate, each right angle arm having lts inner part located perpenicularly of the piston and its outer'part parallel with the piston, collars located near the being adapted to assume a position in line extremities of the right angle arms, coiled r 5 springs secured at then inner ends to said extremities and heads secured to the outer ends of the coiled springs; the outer par-ts of the right angle arms, the springs and the heads 20 with the transverse valves so as to push positively and directly upon the latter.
